From mboxrd@z Thu Jan 1 00:00:00 1970 From: thierry.reding@gmail.com (Thierry Reding) Date: Mon, 5 Oct 2015 10:49:50 +0200 Subject: [PATCH 10/17] ARM: pxa: palmtc: Use PWM lookup table In-Reply-To: <1444034997-9805-1-git-send-email-thierry.reding@gmail.com> References: <1444034997-9805-1-git-send-email-thierry.reding@gmail.com> Message-ID: <1444034997-9805-11-git-send-email-thierry.reding@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Use a PWM lookup table to provide the PWM to the pwm-backlight device. The driver has a legacy code path that is required only because boards still use the legacy method of requesting PWMs by global ID. Replacing these usages allows that legacy fallback to be removed.
